HELP! Klein's Butterfly Has White Growth

Hi There!

I have a 55 Gallon Reef Tank, 9 months old.
Tank Members:

2 Clownfish
2 Pajama Cardinals
1 Bi Colored Blenny
1 Kleins Butterfly
1 Porcelain Crab
1 Black Long Spike Sea Urchin
Green Bubble Tip Anemone
Various Snails and Corals

I just returned from being out of town to find a couple growths on my Klein's Butterfly! She is the latest addition (3 weeks) to my saltwater tank along with Bi Colored Blenny!

I have attached pictures of Jane (Butterflyfish) and I would love any thoughts on what this might be.

I had a freshwater tank for over 6 years but this is my first saltwater tank so if you need any additional information to help with diagnosis, please let me know!

Water levels came back great. Water is clear, temp 75.6, other fish look great.

Jane (Butterflyfish) is continuing to eat (everything in sight:0) and is swimming great! Her eyes look clear and gills/mouth look clean.

The growth appears to be raised on her back fin area on left and right side. She has two scales are her right side that are slightly raised and a white bump on her left body.

I absolutely love her and would love any suggestions or help that can be provided!

Thank you in advance!!!!
